Summary of the invention
The objective of the invention is for provide a kind of efficient height, adjusting range big, can adjust automatically, accurate digital control boring head that precision is high.
For this reason, technical scheme of the present invention is: comprise that slide, flange are connected by bolt with shell, adpting flange is connected with shell by attachment cap, flange, lining, axle sleeve, Locking bushing are embedded on the shell, the cutter head base slides in lining, and the shifting block axle passes shifting block by being bolted on cutter head base, the bearing.
It is characterized in that: be provided with shift fork, axle in the enclosure, axle passes shift fork and fixes by screw, and axle rotates in axle sleeve; Shift fork is provided with two slide grooves, is provided with the shifting block of slip in the groove, and shifting block is connected with cutter head base, knife bar coupling part respectively.
Improvement to such scheme is to be provided with spring in the described slide groove.
Improvement again to such scheme is to be provided with latch segment in the described Locking bushing.
Beneficial effect:
The present invention has changed conventional method, by the axially-movable of lathe boring axle being converted into the radial motion of boring head, merges modern cnc technology, and real low cost, high accuracy, the high efficiency of realizing processed automatically.The application of the automatic boring head of accurate digital control can solve the difficulty of heavy parts in clamping, measurement, adjustment effectively; Merge Numeric Control Technology, feed accuracy can reach 0.001mm, and machining accuracy can reach 0.01mm; Compare with conventional method, processing simple bore, shoulder hole efficient can improve 2-5 doubly, and processing taper hole, groove and composite holes efficient can improve 10-20 doubly.
Knife bar coupling part slide plate is connected with block, and block moves in the slide groove, and spring is housed in the slide, and the block motion makes the spring compression and launches.
Latch segment is arranged in the Locking bushing, by the clamping screw adjustment, the locking attachment cap.

The specific embodiment
As shown in Figure 1, 2, 3, the accurate digital control boring head structure mainly contains following a few part:
1. housing parts: shell 1, lining 2, axle sleeve 34, flange 3, slide 13, pressing plate 27 are connected with adpting flange 5 by attachment cap 6, and adpting flange 5 is connected with the lathe facing head, the housing part of composition lathe.
2. knife bar coupling part: shifting block axle 18 is connected with bearing 17, slide plate 19, and knife bar seat 16 is connected with slide plate 19 by self-centering piece 31, self-centering screw rod 29, T type Connection Block 30 and self profile of tooth, forms the knife bar coupling part jointly, and this part is connected with knife bar.
3. power source part: cutter head base 7, shifting block axle 11 are connected with machine tool chief axis by awl bar 4.
4. enforcement part: 22 common compositions implemented part by shifting block 12, shifting block 20, screw 21, axle 34 and shift fork, and this part is the core that axially-movable is converted into radial motion.
5. protection system: two parts are arranged.The one, form by latch segment 8, clamping screw 9 and Locking bushing 10, lock by adjusting 9 pairs of attachment caps 6 of clamping screw, prevent to become flexible, strengthen the boring head rigidity; The 2nd, to form by bolt 23, spring 24, pin 25 and block 26, block is connected with slide plate 19, and can only slide up and down in slide 13 grooves, and control boring head stroke is protected all the other functional parts.
